YouTube's relationships with music labels have certainly been fraught, but it just managed to reach a truce with one of them... at least, for now. The streaming service and Warner have extended licensing deals that will make sure Warner and its artists get paid for legal streams. The terms of the deal haven't been revealed, but a memo from Warner chief Steve Cooper suggests the label is being particularly cautious this time around. The deals are "shorter than usual," he says, "giving us more options in the future." And there's no mistaking why Warner is reluctant to commit for the long haul -- Cooper is convinced that YouTube is taking a lackadaisical approach to fighting piracy.
